NURS 403 Ch.2 Quiz Introduction to
Quantitative Research Questions With Complete
Solutions
What are some typical features of an experiment? correct
answer: randomizing subjects into groups
collecting data
conducting statistical analysis
______ research is a formal, objective, rigorous, systematic
process for generating numerical information about the world.
correct answer: Quantitative research
Who had the wonderful idea of running classic experimental
designs to test the effectiveness of treatments? Bonus: He is also
noted for adding structure to the steps of quantitative research
(aka: hypothesis, research design, and statistical analysis)
correct answer: Sir Ronald Fischer
He provided the groundwork for experimental research
Quasi-experimental approaches were developed by? correct
answer: Campbell and Stanley
Statistical approaches were developed by? correct answer: Karl
Pearson
What are the 4 common types of quantitative research? correct
answer: Descriptive
Correlational
,Quasi-experimental
Experimental
Which are some characteristics of descriptive research? correct
answer: -Exploration and description of phenomena in real life
situations
-Provides an accurate account of characteristics of particular
individuals, situations, or groups
-Occurs in natural settings
-No manipulation of the situation
- Done to discover meaning, describe what exists, determine
frequency, categorize info
Correlational research involves the systematic investigation of
______? correct answer: Relationships between or among
variables
How is the strength of a relationship in correlational research
measured? correct answer: a scale ranging from -1 (perfect
negative relationship) to +1 perfect positive correlation
A positive relationship indicates variables vary _____ correct
answer: together
both variables increase or decrease together
A negative relationship indicated variables vary in _____ correct
answer: opposition
one variable increases the other decreases and vice versa
, The primary intent of correlational studies is to what? correct
answer: explain the nature if relationships in the real world, not
to determine cause and effect
The purpose of ________ is to examine causal relationships of
determine effect of one variable on another. correct answer:
quasi-experimental
How does quasi-expperimental research studies differ from
experimental studies? correct answer: Level of control
quasi experimental studies exercise less control over the
manipulation of the situation whereas experimental research is
in a highly controlled environment
What is experimental research? correct answer: An objective,
systematic, highly controlled investigation conducted for the
purpose of predicting and controlling phenomena
What is the most powerful quantitative method of research?
correct answer: Experimental research
What are the 3 main characteristics of experimental research?
correct answer: 1. controlled manipulation of at least one
treatment variable (independent variable)
2. exposure of some of the subjects to treatment (experimental
group) and no exposure of the remaining subjects (control
group)
3. random assignment of subjects to the control or experimental
group
